The JQX-40M is a versatile Military Metal Sealing Relay designed to replace three critical legacy relays: LEACH E410 series, M400 models, and Russian P3H33 series. This 4KPa-rated Aviation DC Relay offers superior 10A/28VDC switching capacity, making it an ideal upgrade for high-power aerospace and defense applications.

This relay delivers exceptional value by consolidating replacement parts and enhancing system capabilities. Ideal for: Aircraft power distribution systems, Military vehicle control units, UAV propulsion control, Ground support equipment, and legacy Russian equipment modernization. Its 10A rating makes it suitable for applications where typical Intermediate Power Relays are insufficient.
Manufactured under ISO 9001 quality system in our certified facility. Production follows stringent protocols with 100% electrical testing and batch environmental validation to ensure compliance with aviation and military performance standards.
We offer comprehensive OEM/ODM solutions. Custom coil voltages, pin configurations, and performance specifications can be developed for volume orders, extending the flexibility we provide for our Polarized Relay JH-2S and other specialized lines.
Q: Does the JQX-40M directly fit all three relay footprints?
A: Yes, it is designed as a form-fit-function replacement for LEACH E410, M400, and Russian P3H33 series relays.
Q: What is the advantage of 10A rating over original specifications?
A: The higher current capacity provides additional design margin, improves reliability under load, and future-proofs your systems.
Q: How does this compare to solid-state alternatives?
A: As a Military Metal Relay, it offers superior electrical isolation, surge resistance, and cost-effectiveness for many high-power aviation applications compared to Solid State Relays.
Q: Are samples available for qualification testing?
A: Yes, samples are available for qualified B2B customers to verify compatibility and performance.
